tmckayaignatov, mattf, sorry I missed it.  I was deep in thought about EDP18:46
*** IlyaE has quit IRC18:46
tmckayaignatov, I think there may be a bug with Pig workflows that use arguments.  We have arguments as a dictionary (like params).  I think it's supposed to be just a list of strings.18:46
aignatovtmckay: not a problem at all!18:47
aignatovtmckay: let me quick a look edp code18:47
*** NikitaKonovalov has quit IRC18:47
*** dmitryme has joined #savanna18:47
*** ruhe_away is now known as ruhe18:48
tmckayaignatov, everything I see in Pig Oozie tutorials points that way (and from what I can find in grepcode on the oozie pig launcher).  "params" are turned into additional args and then passed to Pig.  I think "arguments" should not be named.  I'll play, just wanted to give a heads up.18:49
*** NikitaKonovalov has joined #savanna18:50
tmckayour edp-pig example does not use arguments :)  only "params" generated from data sources.18:50
*** openstackgerrit has quit IRC18:52
*** openstackgerrit has joined #savanna18:53
aignatovso we should use arguments instead of params to put input and output to script, right?18:54
aignatovbtw, the good page about pig workflow https://cwiki.apache.org/confluence/display/OOZIE/Pig+Cookbook18:54
aignatovI know Nadya used it when she worked on pig actions18:55
*** NikitaKonovalov has quit IRC18:56
tmckayaignatov, yes, I've seen that.  well, both are okay.  "params" is a shorthand, I think.  They end up being turned into "-param name = value" and the whole thing is passed as an argument18:56
tmckayyou could do the same thing by specifying "-param name = value" yourself in Savanna as an "argument".  But, we force arguments to be a dictionary.  :)  You see?18:57
tmckayI'm suggesting we keep both, but "arguments" should in job_configs for Pig jobs should just be a list of strings18:58
tmckaygoing to play with this on my cluster and make sure I'm sane...18:59
tmckayall this from writing documentation, hehe18:59

tmckayaignatov, anyway, my missing status from the meeting -- finishing up edp.rst changes for java action and hdfs data source, then I'm going to work on the REST doc19:04
*** NikitaKonovalov has quit IRC19:05
tmckayaignatov, also, I will take my integration test out of draft when new savanna python client is available on savanna-ci19:05
*** ErikB has quit IRC19:05
aignatovtmckay: nice update, really!19:05
tmckayI mean the REST doc in reference to java actions and hdfs, not the changes mattf has suggested :)19:06
tmckaynot yet anyway19:06

SergeyLukjanovtmckay, you can already use 0.4.119:08
SergeyLukjanovjust by setting it in the requirements file19:08

SergeyLukjanovwe're installing savanna from scratch each it on savanna-ci19:09
tmckaySergeyLukjanov, ah, okay, thanks!  I'll try that later.19:09

openstackgerritSergey Lukjanov proposed a change to openstack/savanna: Add missed i18n configs to setup.cfg  https://review.openstack.org/6729020:41
SergeyLukjanovaignatov, mattf, please take a look on it asap20:42
*** dmitryme has quit IRC20:53
aignatovSergeyLukjanov, done, why is so asap?20:58
SergeyLukjanovaignatov, our i18n jobs are failing20:58
SergeyLukjanovfor several month :(20:59
tmckayaignatov, crobertsrh, so I was right about arguments for Pig.  It is a list of strings.  <param>n=v</param> is a shorthand for <argument>-param</argument> <argument>n=v</argument>20:59
tmckayhttp://fpaste.org/69099/13899058/20:59
tmckayfrom the oozie logs ^^20:59
tmckayThe "arguments" are essentially for (expert) users to modify Pig execution with Pig options21:00
tmckayI'll make a bug.21:01
aignatovtmckay: good investigation! :)21:04
aignatovbtw, mattf, I'm waiting your review on https://review.openstack.org/#/c/64210 and all dependent patches :) not asap but still21:09
tmckayaignatov, thanks. so it's wrong, but apparently it doesn't break anything.  http://fpaste.org/69108/99066921/.  Looks like Pig ignores the arguments (we put all our args last in Savanna).  I ran this one manually but I'll verify from Savanna.21:14
tmckayso the question is, whether to fix it now.  The only thing lost with it broken is the ability to set specific Pig -options21:14
tmckayIn the fpaste above, I added "Bob=Bill"21:15
*** NikitaKonovalov has quit IRC21:16
aignatovtmckay, I think we should fix it if it breaks something or wrong... not sure if this issue has high priority but should be fixed, imho21:20
tmckayverified, setting bogus arguments from Savanna does not break anything -- the job will still run.21:21
tmckayaignatov, agreed, it should be fixed.  Not sure how hard it is for crobertsrh to change from dict to [], and savanna-api needs changes....21:21
*** qwerty_nor has joined #savanna21:22
tmckayaignatov, 3 work days before the freeze :)  If the freeze is end of the day on the 22nd, then it's 4.21:22
tmckayif it doesn't get fixed, it's not a disaster21:23
aignatovtmckay: no way :), not in this milestone21:23
tmckaylol, that's what I was wondering.  Okay, no pressure then.  That's why I checked whether or not it broke the job.21:24

*** jdev789 has joined #savanna21:31
tmckayaignatov, didn't try yet.  It took a while to run all these Oozie jobs :)21:36
tmckaycrobertsrh, found another related issue.  If you hit the "add" button for arguments on a Pig job but leave name/value blank, you get <argument>=</argument> in the xml.21:43
tmckayNot sure if that's the UIs fault for passing empty name/value pairs, or the api's fault for not ignoring them21:44
